Abstract Objective: To determine the reliability and reproducibility of using three-dimensional (3D) digital models, as an alternative to plaster models for rating dental arch relationships in patients born with unilateral cleft lip and palate (UCLP). Design: Reliability and reproducibility study. Methods: Study models of 45 patients born with UCLP were made available in plaster and 3D digital models. Records were scored a week apart by three examiners using the 5-year olds' Index reference models, in the same two formats as the patient models. To assess reproducibility the study was repeated four weeks later under similar conditions, to minimise the influence of memory bias on the results. The reliability of using the 3D digital models was determined by comparing the scores for each examiner with the plaster model scores. Results: Weighted kappa statistics indicated repeatability for the plaster models was very good (0.83 to 0.87). For the 3D digital models it was good to very good (0.74 to 0.83). Overall the use of the 3D digital models showed good agreement with the plaster model scores, on both occasions. Conclusion: 3D digital models appear to be a good alternative to plaster models for assessing dental arch relationships using the 5-year olds' Index. Key Words: Dental arch relationships, cleft lip and palate, 3D models, dental models.
